I am currently taking Symbicort,
Singulair,
and Flonase,
and most days am able to exercise
and go about my daily business (full-time working mom).
First, what does your doctor say? If you don't trust his/her opinion, get another one. Second, if you have atopic (allergic) asthma, allergies can change, so you might want to get an IgE blood test done to see if you're now sensitive to dust mites, etc. Drainage from sinus allergies and infection can cause asthmatic symptoms, too.
